EPEVER Tracer 4215BN 40A MPPT Controller 12V/24V Auto,Max 150V, 520W/1040W Input with LCD Display for Sealed, Gel, Flooded Lead-Acid Battery

The Tracer-BN series is based on common negative design andadvanced MPPT control algorithm, with die-cast aluminum design for heatdissipation. With MPPT control algorithm, in any situation, products ofthis series can fast and accurately track out the best maximum powerpoint (MPP) of photovoltaic array, in order to obtain the maximum solarenergy in time, which remarkably improves energy efficiency.

With Modbus communication protocol interface, it isconvenient for customers to expand applications and monitor in variousfields like telecommunication base station, household system, caravansystem, street lighting system, wilderness monitoring system, etc.

All-round electronic fault self-test function and enhancedelectronic protection function could furthest avoid damages on systemcomponents resulting from installation errors or system failures.

• Advanced Maximum Power Point Tracking (MPPT) technology, with efficiency no less than 99.5%.
• High quality components, perfecting system performance, with maximum conversion efficiency of 98%.
• Reliable automatic limit function of maximum PV input power, ensuring no overload under any circumstance.
• Multiple load control modes: manual control, light ON/OFF, light On+Timer and time control.
• Support 4 charging options: Sealed, Gel, Flooded and User.
• WithRS-485 communication bus interface and Modbus communication protocol,it is available to meet various communication requirements in differentsituations.
• Available for PCmonitoring and external display unit connecting like MT50 and so on,realizing real-time data checking and parameters setting.

• 1)Connect components to the charge controller in the sequence as shownabove and pay much attention to the "+" and "-". Please don't turn onthe fuse during the installation. When disconnecting the system, theorder will be reserved.
• 2)After installation, power the controller and check the battery indicatoron the controller, it will be green. Always connect the battery first,in order to allow the controller to recognize the system voltage.
• 3) The battery fuse should be installed as close to the battery as possible. The suggested distance is within 150mm.

• 4)The Tracer-BN series is a negative ground controller. Any negativeconnection of solar, load or battery can be earth grounded as required.
• CAUTION: Unplug the RTS, the temperature of battery will be set to a fixed value 25℃.
• CAUTION: Please connect the inverter to the battery rather than to the controller, if the inverter is necessary.
• CAUTION:The RS-485 port and RTS port is not SELV circuit, it must haveisolation between the port and the place where the end user can accessdirectly.

• Package List:
• 1 x Solar Charge Controller
• 1 x User Manual

You can directly contact SolaMr to select for you.



The control you will purchase must meet two conditions

1. The rated current of the controller must be greater than (the power of the solar panel divided by the voltage of the battery)

2. The open circuit voltage of the controller must be greater than the open circuit voltage of your solar panel, and both must be greater than the voltage of your battery
